Loss of trail access is the big ticket. The various trail user groups throughout the US are very heavily anti-MTB. Mountain biker advocacy groups across the US have fought a long hard battle to get what little access we have. As of late, the fight has been going very well, mainly due to the advocacy groups showing that we, as MTB'ers, are willing to work WITH the other trail users and pay attention to the trail restrictions and regulations. Bike companies pushing their agenda with E-bikes and purposely making them nearly indistinguishable from regular mountain bikes just makes the fight harder for the entire MTB group. Keep sneaking these motorized vehicles onto non-motorized trails and watch as everything the MTB advocacy groups have done over the last 30 years get unwound and ALL trails will be hiking and equestrian ONLY.
